0.85 Ct. Bluish Green Sapphire from Montana

This 0.85 carat bluish green sapphire presents a precise balance of size and refined gemological characteristics. The stone measures 6.07 x 5.54 x 3.60 mm and is fashioned in a carefully executed fancy shape that optimizes light return for its proportions. The medium color intensity yields a restrained bluish green tone that is both versatile for settings and indicative of natural Montana material. Heat treatment has been applied to enhance color uniformity, a common and accepted practice that stabilizes the hue without compromising the gem authenticity. Clarity is graded as slightly included at eye level, which is consistent with natural sapphire formation and contributes modestly to character while maintaining overall transparency and brilliance. The polish is assessed as excellent, producing crisp facet junctions and a clean table that improves apparent brightness and faceted contrast.

The weight of 0.85 carat is a key determinant of this sapphires value and rarity. In the market for natural Montana sapphires, stones approaching the one carat threshold are less common, and the near one carat weight of this gem enhances its desirability for both fine jewelry and collection purposes. Weight influences not only monetary value, but also practical options for mounting and design, permitting a variety of settings from solitaire to three stone compositions while preserving the visual presence expected of a primary stone. The combination of weight, calibrated dimensions, and excellent polish results in a gem that sits confidently in a setting without appearing undersized. Provenance further informs value, Montana origin being associated with a distinct color palette and geological history. The Natural Sapphire Company documents this origin and provides condition and treatment disclosure, supporting transparent evaluation and long term appraisal. For buyers seeking a naturally derived sapphire with measured weight and documented attributes, this 0.85 carat fancy shape bluish green sapphire represents a clear example of how weight and quality metrics together define rarity and utility.
